The murderous events in Paris bring to mind the famous words of the German Lutheran pastor, Martin Niemoller. Niemoller spent seven years in a Nazi concentration camp.

This is what he said: First they came for the Socialists and I did not speak out - Because I was not a Socialist. Then they came for the Trade Unionists and I did not speak out - Because I was not a Trade Unionist. Then they came for the Jews and I did not speak out - Because I was not a Jew. Then they came for me - and there was no one left to speak for me.
